dating the age of steel Validating drop down

So I better change that initial selection: choices can be flat out wrong! Yep, we’ll use some code to clear out any ‘downstream’ choices if anything ‘upstream’ changes. In my Dynamic-Dependent-dropdowns-20140214, you’ll see that all the different categories used by the dropdowns are hosted in an Excel Table, that has the categories across the top: So how do these categories get used by the data validation dropdowns? B8, Table1[#Headers],0)): INDEX( Table1, COUNTA(INDEX(Table1,, MATCH(Sheet1! Once it’s found it, it simply uses the items listed underneath that heading.

There are basic instructions on the Getting Started page, and many other techniques, such as Dependent Drop Down Lists, and showing a popup Combo Box when a data validation cell is clicked.

There are many tips in the following sections, for working efficiently with data validation, and troubleshooting tips for when things go wrong.

Previously, we reviewed the Data Validation Feature in Excel 2010, and today I’m going to review the same feature in Google Docs.

On August 26, 2010, Google Docs spreadsheets (aka Google Sheets) added in-cell dropdown and validation in spreadsheets bringing it one step closer to feature parity with Excel. Simple – it constrains the values of a cell to a pre-set list or specific range.

See the step-by-step instructions to see the latest screenshots—the names of the some of the options and settings have changed.

A validation object includes a list of form elements, and rules to validate each against.

Or, make " --Select--" the top item in the Product list, and set up the worksheet with " --Select--" entered in each product cell, as the default entry.

NOTE: Type a space or an apostrophe at the start of "--Select--" so Excel will not show you an error message.

All you need to do is simply add the new subcategories to the right hand side of our validations table (Table1). If you look at the below screenshot, you’ll see that users can choose from a number of different kinds of meat: Let’s add a further level that would give meat eaters some further choices relating to . This blog is started in 2007 and today has 450 articles and tutorials on using excel, making better charts.

To set this up, all we need to do is take the individual items from that ‘Meat’ column and add each one as a new column header: Then we simply list the new options for each type of meat below the relevant header: Now here’s the magic: as soon as we add another column to our input table and set it up with data validation – which I did simply by clicking on the bottom right corner of the cell with the word ‘Human’ and dragging it across – then Excel picks up on the fact that there’s a sub-subcategory, and serves it up to us. As mentioned earlier, in addition to Roger’s great method, I’ve written some code that clears out any downstream entries in the event that an upstream entry is changed. Calculation = xl Calculation Manual End With For Each target Cell In Target 'Clear any cells that use 'Sub List' to the right of target Cell in the current table.

These validation prompts are also set to appear on input change instead of form submission.
